ADSORPTION STUDIES OF POMEGRANATE PEEL ACTIVATED CHARCOAL FOR NICKEL (II) ION

Presence of toxic heavy metals in air, soil, and water are growing threats to the environment. In this study, removal of divalent nickel from aqueous solutions has been investigated by utilizing a low cost pomegranate peel activated charcoal (PPAC) adsorbent. Adsorption capacity of the prepared char...
